To all whom t may concern:

Be it known that I, EDWARD C. MORRISON,- citizen of the United States, residing at Fayetteville, in the county of Onondaga and I State of New York, have invented certain new and useful Improvements in Car-Journal-Polishing Devices, of which the following is a specification. This invention relates to certain new an useful improvements in car polishing devices and has particular. reference to devices of that kind that are portable and ca able of being readily applied to or removed om the journals. l

The primary object of the invention is-to generally simplify and improve devices of the above character whereby the same may meet with all of the requirements for a successful commercial use.- Another object is to provide a portable car journalling device by means of which the journal may be evenly and uniformly polished.

Still another object of the invention is to 2l provide a polishing device capable of being positioned upon a car journal and accurately centered thereon whereby, upon rotation of the device bodily about the journal, the latter will be uniformly polished.

' A still further object of the invention is to provide means for effectively preventing displacement of the device from the car journal when operatively disposed upon the latter, and to provide means whereby the pressure with which the polishing elements engage the` car journal may be effectively regulated to the desired degree.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views:

Figure l is a side elevational view of a polishing device constructed in accordance with the present invention and shown applied upon a car journal.

Fi ure 2 1s a transversesectional view of the evice shown in'Figure 1, taken'to'the Vthree revolutions about the latter.

rigit 'hand side of thepulley .in said ligure, an f Figure '3 is an elevational view frame ring of the device.

Referring more in detail to the'dr'awings, the usual car journal 5 is enlarged asiat 6 at its inner end portion 'adjacent its connection with the wheel 7v and is providedwith an annular outwardl directed flan e8 upon its outer free end. e object of t e invention is to provide a device for polishing these journals.. y'

The invention embodies a cylinder linl the forml of arigidy open frame, composed of an outer end disc or ring 9 and an inner ring 10 that are ri idly connected in parallel spaced Vrelation y a plurality of rods 11, 12 and 13, provided in pairs as shown clearly in Figure 2 and (positioned adjacent the outer edges of sai rings 9' and 10. The rings 9` and 10 are preferablyv provided with transverse openings in which reduced ends of the rods 11,12 and 13 are secured in any suitable manner as by riveting lor the like, and the rods 11, 12 and A13 are of such leng'h .y

of the inner as to (position the disc or ring 9` outwar of an spaced from the flan e 8 of the car journal when the ring 10 is isposed to sur-v round the enlarged portion 6 of said journal.

The ring 10 1s rovided with a plurality of radial adjustab e screws 14 having operating handles at their outer ends at 15 and provided with rollers 16 upon their inner ends adapted to be adjusted as to contact with the portion 6 of the car journal, whereby the innerend of the device is anti-frictionallyl mounted upon the portion 6 for Obviously'by proper manipulationof the screws 14, the ring 10 may be adjusted to a position wherein the same is concentric with said journal portion 6.

The ldisc or ring 9 is provided with a relatively small central circular opening/17 in vwhich is loosely fitted a bushing 18l that is flanged at its inner end as at 19, for preventing displacement of the bushing outwardly through the opening 17, and this bushing is internally threaded for adjustable reception of a central screw 21. The screw 21 -is threaded throu h the bushing 18 and has its inner end suitab y formed as at 22 to provide a anti-frictional engagement thereof with the center point or socket in the outer free end of the journal 5. The outer end of the screw 2l is preferably reduced for the reception of a loop form of handle 23 which is secured upon said reduced portion by means of a nut 24 threaded on the latter outwardly of the portion of the handle which is disposed upon said reduced portion of the screw as shown in Figure l. The portion of the screw 2l upon which the handle 23 is disposed is preferably of angular forni in cross section similar to the openings through the handle so that the screw 21 may be rotated upon r0- tation of said handle.

Extending inwardly through openings in the disc 9 inwardly of the rod 1l are a pair of pintles 25 that have inturned inner ends as at 26 upon which are journalled antifriction. rollers 27 arranged to bear against the inner surface of the flange 8 whereby this end of the device may freely rotate about the journal and at the same time be held against outward longitudinal displacement from saidjournal. rfhe pintles 25 are logitudinally adjustable through the ring or disc 9 and this adjustment is secured by means vof nuts 28 threaded upon the outer ends ofsaid pintles against the outer surface of the ring or disc 9 as shown in Figure 1.

A plurality of spring arms preferably constructed of strips of resilient metal have their outer ends rigidly attached to the rods 1Q, and these arms which are indicated at 29 are arranged tangentially of the :frame of the device as shown in Figure 2, with their free inner ends suitably engaging the outer surfaces of a pair of opposed polishing strips 30 that are arranged longitudinally of the device and of suc-h length as to engage the major surface of the journal 5. If desired, the polishing elements .may be secured to the arms 29 although it is only necessary thatsaid arms be formed with inturned free ends as at 3l, to retain the same. Each polishing strip 30 is preferably engaged by a pair of the arms 29 as shown, and said polishing strip will thereby be yieldingly held with a certain amount of pressure, into engagement with the journal. As this pressure will lessen as the polishing strip wears, it is desirable to provide means for adjusting the tension of said arm 29. This is preferably accomplished by means of adjusting screws 32 threaded through the rods i3 and having their inner ends bearing upon the arms 29 as shown, the outer ends of the screws 32 being equipped with handles 33 by means of which they may be manipulated.

The several rods, or if found more desirable, the pair of rods ll may be utilized for supporting a ring like pulley 34: midway between the ends of the cylinder or frame of the device to serve as means for facilitating the application of power or rotation to the device whereby the latter may be bodily rotated about the car journal. As shown, the pulley is provided with inwardly projecting lugs 35 that are transversely apertured for slidable `reception vupon the rods ll, said lugs being provided with set screws 36 by means of which the pulley may be secured in proper position between the end members or rings 9 and l0.

In operation, the device is bodily slipped over the car journal until the ring4 10 surrounds the enlargement l2 thereof. The screws 11i are then adjusted inwardly until the rollers 16 engage said enlarged portion 6 of the journallwith the ring l() disposedL concentric with the portion 6 and freely rotatable about the latter. The journals 25 are then swung so as to position the inturned ends 26 thereof behind the flange 8 whereupon said journals are adjusted outwardly to engage the rollers 27 with the inner surface of said flange 8. The center screw 21 is then adjusted inwardly to kengage in the socket provided centrally in the outer end of the car journal whereupon the entire device is positioned so that the journal is centered within the saine,` and Whereby the entire device may be bodily rotated with ease about the journal. Power is then applied to the device for rotating the saine by means of a belt applied to the pulley 34 and passing around apulley, (not shown) carried by any suitable drive` shaft. 0bvieusly, any suitable gearing may be substituted in lieu of the belt and the pulley 34. With the screws 32 adjusted to the proper degree, the opposed polishing strip 3l will yieldingly engage the surface of the journal with an even pressure, and the journal will j be uniformly polished. To remove 'the device, the pintles 25 are loosened and turned,k so as to clear the flange 8, and after the screws 14 are adjusted outwardly, the device may be slid olij of the journal by forcing the arms 29 and the-polishing strip 30 outwardly to clearsaid flange 8.

ln view of the above, it will be seen that l have provided a very simple, durable and eilicient form of journal polishing device, wherein a uniform polishing operation `is had7 in a simple and expeditious manner.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

A portable car journal polishing device comprising a pair of end frame members rigidly connected in parallel spaced relation by mea-ns of longitudinal frame bars1 means to center the inner end of the car journal within Lone of said end frame members, a center screw engageable in the center socket in the outer end of the car journal for centerin the outer end of said journal others of said bars and having their free Within t e outer end of the frame, a ring ends urging the polishin strip toward the pulle mounted upon certain of said rods journals, and means to a just the tension of 10 for acilitating application of rotation to said spring arms toward the journal.

I said frame, lonltudinal polishing elements In testimony whereof I afiix my signadisposed inwar y of the longitudinal frame ture.
